⚙️ How They Work
-
Electric Furnace: Uses electric resistance coils to heat air. A blower then distributes warm air through your ductwork.
-
Gas Furnace: Burns natural gas or propane in a combustion chamber. The resulting heat warms a heat exchanger, and a blower pushes the air into your ducts.

💸 Installation Cost Comparison
Furnace Type | Average Cost (Unit + Install) |
---|---|
Electric | $2,000 – $4,000 |
Gas | $3,000 – $6,500 |
-
Electric: Lower upfront cost, easier installation (no flue or gas line needed).
-
Gas: Higher install cost but potentially lower operating cost if natural gas is cheap in your region.

⚡💨 Energy Efficiency and Operating Cost
-
Electric Furnaces: Nearly 100% AFUE (Annual Fuel Utilization Efficiency) because no heat is lost through flue gases. However, electricity is often more expensive per BTU than gas.
-
Gas Furnaces: High-efficiency models can reach 95–98% AFUE. In areas with low gas prices, this often results in cheaper monthly bills.

🌎 Environmental Impact & Safety
-
Electric: No on-site emissions, making it safer and greener in regions powered by renewable energy. No carbon monoxide risk.
-
Gas: Requires proper venting to avoid CO poisoning and releases combustion emissions, though still regulated.
